Nano-mechanical behavior of MnTiO3 ceramics

Here we investigate the mechanical behavior of the MnTiO3 ceramic. Nanoindentation tests on a manganese titanate polycrystalline sample were performed using a Berkovich indenter with a tip radius of 150 nm. On applying the load, it shows the elastic and plastic behavior. The work done during the elastic and plastic processes are 16,757 +/- 120 mu N.nm and 10,045 +/- 120 mu N.nm, respectively. The estimated values of reduced modulus and hardness are 158 +/- 8 GPa and 10.5 +/- 2 GPa, respectively. This suggests that this compound exhibits a significant plastic character.
